Detailed Description

MeshViz Class to define non linear data mapping.

This class is used to define non linear data mapping. This object defines a non linear association between colors, transparencies and floating-point values. In other words, this association is defined by 2 functions F(c,v) and F(c,t):

         F(c,v)(V) = C (with c being a color and v being a value).
         F(t,v)(V) = T (with t being a transparency and v being a value).
   

F(c,v) and F(t,v) are given by the user. If they are not given by the user, default one are used. The default F(c,v) computes a linear data mapping between black and white. The default F(c,t) returns always 0.

PbNonLinearDataMapping::PbNonLinearDataMapping (  ) 

Default constructor.


Member Function Documentation

void PbNonLinearDataMapping::setHLSFunction ( const float *(*)(float)  func  ) 

deprecated.

void PbNonLinearDataMapping::setHLSFunction ( HLSFunction func,
void *  userData 
)

Sets a non linear function for data mapping.

This function returns a HLS color.

void PbNonLinearDataMapping::setRGBFunction ( const SbColor *(*)(float)  func  ) 

deprecated.

void PbNonLinearDataMapping::setRGBFunction ( RGBFunction func,
void *  userData 
)

Sets a non linear function for data mapping.

This function returns a RGB color.

void PbNonLinearDataMapping::setTransparencyFunction ( float(*)(float)  func  ) 

deprecated.

void PbNonLinearDataMapping::setTransparencyFunction ( TransparencyFunction func,
void *  userData 
)

Sets a function returning a transparency value.

If no function is set, a default function is used (returning always 0.0).
